This package contains a number of standard				 * shapes that can be used that can be directly added to the scene graph, or				 * combined to build up more complex shapes.				 * 				 * An important point to note about all of the shapes in this package is that				 * once they have been created they calcuate all of the geometry required for				 * their tri-mesh representation. This has a couple of implications:				 * 				 * 				 * the property accessors represent the values that the shape was created with (or the				 *     values from the last update if it has been updated), there is no guarantee that the				 *     actual shape will not have been altered via other means such as calling the methods				 *     on {@link TriMesh} directly; and				 * many of the shapes offer a single methods that sets multiple data values in one hit,				 *     for example {@link Sphere} provides the {@link Sphere#updateGeometry(com.jme.math.Vector3f,				 *     int, int, float)} method. If you are going to update more than one value it will be				 *     considerable more efficient to do so via these methods instead of the individual				 *     property mutators.				 * 				 * 				 * @author Ian Phillips				 * @version $Revision: 4075 $, $Date: 2008-12-19 21:05:33 +0800 (星期五, 19 十二月 2008) $				 */				package com.jme.scene.shape;
